A tight surface pressure gradient set up across eastern North Dakota and portions of the northwest quarter of Minnesota, between an area of surface low pressure over west central South Dakota and a high north of the Great Lakes. Evening upper air observations on the 5th and morning upper air observations on the 6th measured 60 to 70 mph wind speeds just off the surface. Some of these 60 to 70 mph wind speeds were pushed down to the surface across southeast North Dakota and portions of west central Minnesota, causing scattered tree and property damage. Rain showers helped to mix the stronger winds down to the surface.
